Dr. Stone is one of those shows that I never seek out to watch, but every time I put it on I'm thoroughly entertained. If you enjoyed the previous seasons, you’ll like this one too. However, if there's any gripe I have that's worth pointing out with this season compared to the previous ones, it's the fact that some of the science stuff is beginning to get a little bit "incomprehensible". An aspect that I (a science nerd) really enjoyed with the earlier seasons was how many concepts and technologies of modern civilizations were explained by simple, primitive science. Now that the fictional civilization hasbeen established, the show has kind of moved past that, and the science used is gradually becoming more and more obscure. At the end of the day, the story must develop, so the ends partly justify the means in this case.

7 / 10, yes, the Ryuusui special is canon, so watch that first.
